Description

[Detailed description of the invention] This invention, regarding power distribution boards such as control panels, monitoring panels, operation panels, display panels, etc., simplifies the installation and removal of some of the components of the power distribution board, facilitates maintenance, and provides a beautiful appearance. This is what I did.

Conventionally, as shown in FIGS. 1 and 2, in this type of switchboard, a metal box 3 is fixed to a board 2 on a base 1, and various instruments are housed inside the box 3. An opening 5 is formed in the front plate 4 of the box body 3, an operation panel 8 equipped with parts such as various switches 6 and indicator lamps 7 is attached to the opening 5, and a door 9 is provided on the back side of the box body 3. . To attach the operation plate 8 to the opening 5, as shown in FIG.
1 and screw the nut 12 onto the bolt 10 from the back side of the front plate 4, or as shown in FIG. A bolt 14 is inserted into the through hole 11 of the front plate 4, and a nut 12 is screwed onto the bolt 14 from the back side of the front plate 4.

Therefore, when installing the operation panel 8, the box body 3
The nut 12 must be screwed in from the rear side, which is difficult. In addition, when performing maintenance on the back side of the operation panel 8, open the door 9 and tighten the nut 1.
2 and the operation panel 8, which is troublesome and, if a large instrument is housed in the box 3, there is little space and the operation is difficult. Furthermore, in the case of Figure 3, bolt 1
4 is exposed on the surface side of the operation panel 8, which is unfavorable in terms of appearance.

This invention has been made with the above-mentioned points in mind, and next, this invention will be explained in detail with reference to the drawings from FIG. 4 showing one embodiment of the invention.

A metal base 15 such as an iron plate or a stainless steel plate is fixed to a substrate 2 on a base 1. This base 15
consists of a top plate 16, an L-shaped side plate 17, and a narrow back plate 1.
8, a front opening 19 is formed on the front surface, and a rear opening 20 is formed on the rear surface side. On the other hand, a front box 21 and a rear box 22 made of synthetic resin and having at least one side open are manufactured by vacuum forming. The front box body 21 may be opened only on the back surface, or may be opened on the back surface and the bottom surface. The rear box body 21 has an open front and bottom surface. The outer shape of each opening of both the boxes 21 and 22 is the same as that of the front opening 1 of the base body 15.
9. An insertion slot 2 that is the same as or slightly larger than the inner shape of the rear opening 20 and is indicated by diagonal lines in FIG.
1' and 22' are formed, respectively. Further, as illustrated in FIG. 6, a stopper 23 is appropriately provided on the inner surface of the base body 15, and parts such as a switch 6 and an indicator lamp 7 are mounted on the front plate of the front box body 21.

When attaching both the boxes 21 and 22 to the base 15, use the flexibility of the synthetic resin to slightly press the openings of each box 21 and 22, and
into each of the openings 19 and 20 until it abuts against the stopper 23. After insertion, due to the restoring force of each box body 21, 22, the insertion margins 21', 22' are aligned with the base body 15.
The box bodies 21 and 22 are attached to the base body 15 by being in pressure contact with the inner surface of the base body 15. In addition, each box body 21, 22 is connected to the base body 15.
When removing from the box, it can be easily removed by slightly pressing each box 21, 22 and pulling it out.

As mentioned above, this idea consists of a board on a base, a top plate, an L-shaped side plate, and a narrow back plate, with a front opening on the front side and a rear opening on the rear side. A flexible front box made of synthetic resin with an open back is fixed to the front opening, a stopper is provided inside the periphery of both openings, and a flexible front box made of synthetic resin with an open back is placed in the front opening. This is a power distribution board in which a flexible rear box body is inserted into the rear opening by pressing the insertion margins formed at the opening peripheries of both boxes until they abut against the stoppers.

Therefore, according to this invention, the box can be attached to and removed from the base very easily by taking advantage of the flexibility of the box, and the back side of parts such as switches and indicator lamps can be maintained by removing the box. It can be done easily. Moreover, since the box body is made of synthetic resin,
It is beautiful, and the paint won't peel off like with metal, so this design is particularly easy to maintain and has a good appearance.
